Providing up to 5 million passenger journeys a day, the London Underground is integral to the city's infrastructure. It's impossible to imagine how the city would function without it.
But why would something built for purpose become a source of admiration and entertainment? A Transport for London style guide provides powerful evidence: "Every Underground station should include at least one moment of delight and surprise, to improve customers' journeys and the working environment for staff."
A-ha!
Let's meet some Tube superfans.
Jen tells a story about Underground trainspotters and highlights the Tube in pop culture, while Mares looks at people who attempt the citywide Tube Challenge.
We'll think about the nature of challenge, the history of tube spotting and racing challenges, and some of the unique and engaging personalities for whom the Tube (and Overground) truly is a constant delight and surprise.
